Issue body
### Bug Description
"snapcraft extension" does not accept a core22 extension as an argument. Here, ros2-humble is a valid core22 extension:
$ snapcraft extension ros1-noetic
Setup a ROS 1 build and runtime environment suitable for a snap.
$ snapcraft extension ros2-foxy
Drives ROS 2 build and runtime environment for snap.
$ snapcraft extension ros2-humble
Failed to find extension 'ros2-humble': a extension by that name does not exist.
Check the extension name and try again.
$
This despite the fact that "snapcraft extensions" clearly lists ros2-humble as a valid core22 extension. Same problem with the other core22 extensions:
$ snapcraft extension gnome
Failed to find extension 'gnome': a extension by that name does not exist.
Check the extension name and try again.
$
### To Reproduce
$ snapcraft extension ros2-humble
$ snapcraft extension gnome
### Environment
Ubuntu 22.04, snap 7.5.2
### snapcraft.yaml
```shell
None.
```
### Relevant log output
```shell
None.
```
### Additional context
